– Position the measuring tool (without turn-

ing it) at a distance of 5 m so that the

crossing point of the laser lines is on the

already marked point II and that the 0°

laser line runs through the point III.

Mark the centre of the 90° laser line at a

distance of 5 m (Point IV).

– Turn the measuring tool by 90° so that

the centre of the 0° laser line runs

through the point IV.

The crossing point of the laser lines must

still be on the point II.

– Mark the centre of the 90° laser line at a

distance of 5 m as point V as near as pos-

sible next to the point I.

– The difference d of the two points V and I

is the actual deviation of the 0° laser line

and the 90° laser line from the right angle.

The measuring length 2 x 5 m = 10 m has a

maximum admissible deviation of:

10 m x ± 0.2 mm/m = ± 2 mm.

Therefore, the maximum difference d be-

tween the points I and V may be 2 mm or less.

Checking the angular accuracy between

the 0° and the 45° laser lines

– Position the measuring tool in one of the

corners of the measuring surface. Switch

on the measuring tool and align it so that

the 0° laser line runs along the long side

of the measuring surface and that the 90°

laser line runs along the short side of the

measuring surface.

– Mark the crossing point of the laser lines

on the floor (Point I). Mark also the centre

of the 0° laser line at a distance of 5 m

(Point II) and at a distance of 10 m

(Point III).
